Total Knee Arthroplasty

Easy, precise and accurate

The continuous improvement of the software for navigated TKA is closely designed in partnership with OrthoPilot® users.

TKA Features

  • The implantation result as well as the resulting soft tissue situation can be stimulated with an interactive planning tool 
prior to resection
  • Improved load distribution across the implant
  • Increased prospective implant longevity
  • Improved postoperative joint function
  • Increased mobility and stability
  • An improved algorithm achieves superior accuracy in the calculation of the joint centers
  • The high-tech instrumentation for navigation supports the surgeon during the procedure
  • All Aesculap knee implant systems, including the Columbus and e.motion knee system, can be navigated with OrthoPilot®

Software Elements

Kinematic data acquisition

The kinematic acquisition is the guarantee and therefore an important factor for an optimal surgical result. To compute the mechanical centers of the hip, knee and ankle joints, a camera tracks the movement of the markers fixed to the bone.

Palpation of anatomic landmarks

In addition of the kinematic acquisitions, anatomic bone landmarks are palpated. Anatomic landmarks are prominent structures, such as the anterior cortex. Due to the redundancy the result is further optimized.

Tibial resection

The position of the femoral resection can be adjusted with the cutting block according to:

  • Varus/valgus
  • Anterior/posterior tibial slope
  • Medial and lateral height of resection

After the resection, the position and alignment of the final cutting plane is confirmed with a measuring plate.

Gap measurement

The joint gap is measured by distraction of the medial and the lateral gaps, independently first in extension and then in flexion.  At the same time the mechanical axis in extension is displayed, this is an indication of the current soft tissue situation.

Femoral resection planning

This feature allows the prospective planning of the resection considering the size and positioning of the femoral component, including ligament situation. This step precedes the actual execution of the femoral cuts. It allows simulating the ideal outcome for the patient in the given situation.

Femoral resection and rotation

The position of the cutting block can be adjusted, according to:

  • Varus/valgus
  • Anterior/posterior slope
  • Distal resection height

After the resection, the position and alignment of the final cutting plane is validated.

Adjustment of femoral rotation according to:

  • Posterior condyles
  • Epicondyles
  • Whiteside line
  • Soft tissue balancing

Remaining gaps in extension and flexion, media and lateral are displayed.
